Premium 7075-T6 Aluminum Lower Link Arms – 36.75″ Length, 2.25″ Solid Diameter
Elevate your off-road suspension with our solid billet lower link arms, precision-machined from aerospace-grade 7075-T6 aluminum. Ideal for demanding 4-link setups and extreme rock crawling builds where maximum strength, minimal weight, and superior resilience are essential.
These lower link arms feature a fixed length of 36.75 inches (no custom sizes available) and a massive solid 2.25-inch diameter for outstanding torsional rigidity and bending resistance under heavy loads.
Why 7075-T6 Aluminum Stands Out:
Exceptional strength-to-weight ratio: Ultimate tensile strength up to 83,000 psi — stronger pound-for-pound than many steels.
Excellent “memory” properties: Flexes under severe impacts and returns to original shape, reducing the risk of permanent deformation compared to steel.
Strength Comparison to 2″ × 0.250″ DOM Steel Tubing: The solid 2.25″ cross-section provides over 2.3 times greater sectional moment of inertia than a 2″ × 0.250″ wall DOM tube, resulting in dramatically higher resistance to bending. Even accounting for aluminum’s lower modulus of elasticity, these links deliver comparable or superior overall stiffness in many loading scenarios while significantly reducing unsprung weight for improved suspension articulation, handling, and reduced component fatigue.
Key Features:
Fixed length: 36.75″ (no custom sizing)
Solid 2.25″ diameter billet construction
Premium 7075-T6 alloy for ultimate durability
Machined ends ready for threading to accept standard heim joints or rod ends (sold separately)
Perfect for serious builders pushing their rigs to the limit on the rocks. Leave bent steel links behind and upgrade to lightweight, high-performance aluminum that keeps performing hit after hit.
